So I drove the car a bit more and realized that although a bit of coolant is coming from the water pump, most of it is coming from the head gasket area above the thermostat. I found the FSM, and another thread on head gasket change. I know I need a head gasket, exh man gasket, intake man gasket, valve cover gasket, and thermostat housing gasket. Any other parts I should order ahead of time? I already have a new set of glow plugs to throw in my current head (provided my head is not cracked).
